"Hello Marek
We understand it and have in plans adding MAVLink protocol. But still we have lot of requests from local market where MAVLink is almost unknown and not used."

"Coordinates (GPS longitude and latitude) can be  displayed with command "G". Flight mode has own control, but at this time not accessible from API. The "Auxiliary text" can be used to display mode. Screen channel in my opinion is not necessary. OSD…"

"turdsurfer: Our OSD can work with other systems, only requirement is access to the code and possibility to implement few commands to send data to OSD. It has published API so if you have free UART port and can implement above protocol, the OSD will…"

"Doug: Coordination of up to 8 runeways are stored in OSD, so it doesn't need to receive external data. Ground station is not necessary. It receive and store information about plane positon from OSD important for documentation purposes and in case of…"

"Hugues, thank you for recommendation.
I am not manufacturer of that tubes, so can't do 0,5mm thin tube. My manufacturer also doesn't do it. Look for local composite companies, but it could be very costly."

"This OSD can work with other systems like APM or Pixhawk. It has open protocol, so if you supply the data from autopilot (artificial horizon, altitude, speed, variometer, compass, GPS pos etc), it will display it. Just you need one free UART and…"

"> Can you store with this module raw L1 phase data?
I can't, or at least don't know how to do.

> these modules have only NMEA  output with four decimal digits [...]
Yes, you are right. This is also MTK chipset, maybe it also have other possible…"

"I am not sure about compatibility. Don't have APM nor PixHawk (but have also GPS module with magnetometer). The GLONASS receiver except standard NMEA messages has additional messages like this:…"
